Slect true or false for each
![The stickleback is a fish native to many coastal waters throughout North America, including Oregon.
It shows many phenotypic variations, making it ideal for studies in evolution and population genetics
(including here at UO). Suppose that a single population of stickleback lives in a local pond. Drought
causes much of the pond to dry up, leaving behind two smaller ponds (Pond 1 & Pond 2). 500 of the
sticklebacks are in Pond 1 and 50 of the sticklebacks are in Pond 2.
Below is a simulation of how the frequency of a particular allele might change over 500 generations
in the fragmented stickleback population. The lines are labeled: pond 1 and pond 2 and the initial
allele frequency was set to 0.5.

Given that genetic drift is the only evolutionary force acting on these populations, which of the
following is true? For each answer, select either true or false.
The A allele only became fixed in Pond 2, so
[ Choose ]
Pond 2 sticklebacks are more fit than Pond 1
sticklebacks.
Pond 1 contains a larger population, so allele
[ Choose ]
fixation and loss are less likely than in Pond
2.
Since the A allele became more frequent in
[ Choose ]
both ponds, fixation of the A allele is more
likely than loss.
The loss of genetic diversity is more likely in
[ Choose ]
Pond 2 than in Pond 1.
